The Study Evaluating Efficacy And Tolerability Of Veliparib in Combination With Temozolomide or In Combination With Carboplatin and Paclitaxel Versus Placebo in Subjects With BRCA1 and BRCA2 Mutation and Metastatic Breast Cancer

Official Title ICMJE

A Randomized, Phase 2 Study of the Efficacy and Tolerability of Veliparib in Combination With Temozolomide or Veliparib in Combination With Carboplatin and Paclitaxel Versus Placebo Plus Carboplatin and Paclitaxel in Subjects With BRCA1 or BRCA2 Mutation and Metastatic Breast Cancer

Brief Summary

The Study Evaluating Efficacy And Tolerability of Veliparib in Combination with Temozolomide or Veliparib/Placebo in Combination with Carboplatin and Paclitaxel in Subjects with locally recurrent Breast Cancer not amenable to therapy with curative intent, or metastatic breast cancer and a documented (BRCA1) and (BRCA2) deleterious germline mutation.

Detailed Description

Subjects will be randomized in a 1:1:1 ratio to one of the three treatment groups. The safety of each treatment group will be assessed by evaluating study drug exposure, adverse events, serious adverse events, all deaths, changes in laboratory determinations, and vital sign parameters. The Clinical Benefit Rate (CBR) and Objective Response Rate (ORR) as well as Progression-free survival (PFS) using Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 will be assessed. Study visits will be conducted according to the protocol schedule and randomization group. Study visits will include physical examination, laboratory blood sample collection, and assessment of vital signs, medical history and urinalysis. 12-lead Electrocardiogram (ECG) will be performed at protocol specified visits.

Histologically or cytologically confirmed breast cancer that is either locally recurrent or metastatic.

Locally recurrent disease must not be amenable to surgical resection or radiation with curative intent.

Must have a documented deleterious Breast Cancer Gene BRCA1 or BRCA2 germline mutation.

If Human Epidermal Growth Factor Receptor (HER2) positive, subjects must have received and progressed on at least one prior standard HER2 directed therapy or the subject must be ineligible to receive anti-HER2 therapy.
